Manual architecture documentation is a chronic source of technical debt. As code evolves across repositories, Visio or Lucidchart diagrams become stale, creating misalignment for new engineers, auditors, and cross-functional teams. This drift introduces onboarding friction, compliance gaps, and costly rework when assumptions about system boundaries and data flows are wrong. The business cost is measured in lost engineering hours, delayed projects, and the latent risk of decisions made from an inaccurate map of the system.
